Our climate solutions offer high levels of impact with high levels of quality.

Why invest through Callirius

There is a shortage of access to high-impact and high-integrity climate projects. Mainly due to the lack of regulation, of independent quality assessment, and of constant external monitoring & verification of project progress.

Additionally, project owners are reluctant toward corporate investors due to historical cases of greenwashing and disregard of actual project needs and conflicting interests. To solve this issue, Callirius builds a high-quality project portfolio to match the needs of both project owners and investors while ensuring high integrity and educating stakeholders on decarbonisation and compensation claims.
